One of the things that Trek has done a couple of times now is have some kind of repeating time loop in which people gradually become aware that they are doing the same thing over and over. But this is nonsensical - if time "resets" itself then your memory would reset also, leaving you with no memory of what had happened even if you had done it a million times before. And if it is just that you have been sent back in time, then your memories of what you had done before would be just as good as ever. Either way this gradual sense of deja-vu could not happen.

Great Moment :

One of the things that Enterprise has done a few times now is use a nearby Vulcan ship as a convinient plot resolution. As in "Fallen Hero", where the bad guys are chasing Enterprise and our heroes just have to hold on until they can reach the almighty Vulcan ship to be safe. When they did it yet again in this episode I thought it was beginning to get a little cliche, but then they turned it around and made it into a nice sting by having Enterprise reach the Vulcan ship and find it had been disabled.

Body Count :

Quite a few Suliban cell ships were destroyed by the Tholians, with probable casualties in the region of a few dozen.

Factoid :

This episode establishes canonically that the Tholians are non-Humanoid, and are comfortable at a temperature of more than two hundred degrees. This is something that was implied but not categorically stated in the original series episode "The Tholian Web", and has been a long-standing assumption in the novels and other spin-offs.

Plotline

Enterprise is now far beyond the limits of past Human exploration, yet when they find a small derelict ship and bring it aboard, a Human corpse is found inside. Mystery piles upon mystery as the vessel itself proves be considerably larger on the inside than it is on the outside. Before the crew can make any headway with the problem, however, the Suliban arrive to claim the ship as their own - and they're not the only ones...
